It is often stated by proponents of "IP/IT/IS" that the techniques of aikido (and presumably other styles) are unimportant; that "IP/IT/IS" operates outside of technique.

In my very limited experience, I would have to say I disagree. In my admittedly short exposure to "IP/IT/IS" I found that everything shown was technique based. It may not be what many would call a formal technique, but technique I believe it is. In my opinion, it really comes down to what distinctions the practitioner is able to make.

Any thoughts?

What do you mean by technique? I think that might help frame the discussion.
